Chapter 9: Column Analysis and Design

Theoretical K-value: K = 2.0 Effective length: L e = 2.0 L P critical = π 2EI min /(2L) 2 = π2EI min /4L 2 Examples: Water tank mounted on a simple pipe column; flagpole. Case E: Both ends are fixed with some lateral translation. Theoretical K-value: K = 1.0 Effective length: L e = 1.0 L P critical = π 2EI min /L 2 Examples: Flexible column attached to a rigid beam and supported by a fixed ... ................
